EF1 tornado, Springfield to Poseyville, Indiana, July 9, 2024

1. EF065 to 85 mph

   Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

2. EF186 to 110 mphthis tornado

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. EF2111 to 135 mph

   Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

4. EF3136 to 165 mph

   Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The remnants of Hurricane Beryl tracked north-northeastward to the Quad State region on the 9th, with the center of circulation following near the Lower Ohio River. The bulk of the stratiform precipitation was northwest of the Quad State, keeping flooding issues from developing. On the eastern flank of the storm, supercellular structure developed on the north end of the lakes in Kentucky, then tracked northeastward, crossing into Southwest Indiana at Mount Vernon after producing two tornadoes in Union County, Kentucky. ||The first SW Indiana tornado rapidly strengthened into an EF-3 as it damaged a large Kenco facility. The tornado overturned train cars and trailers near Old Hwy 62 as it departed from Mount Vernon, causing tree damage further north. This was the first EF-3 tornado in the NWS Paducah County Warning Area (CWA) in July, with records going back to 1950. The tornado cycled multiple times in Southwest Indiana, with tornado paths beginning near Springfield (an EF-1), and again north of Poseyville (an EF-2). For the latter, the damage path broadened as it approached Johnson and leveled several structures. The Johnson tornado narrowly missed the KVWX radar, crossing 1.5 miles to the west. One last brief EF-1 tornado formed on the west side of Patoka from the primary cell. A cluster of storms further east produced a brief EF-1 tornado south of Francisco. The 7 tornadoes from this day (5 in Indiana, 2 in Kentucky) were a single day record for July tornadoes in the NWS Paducah CWA.||Effective bulk shear was near 50 kts when the tornadoes developed, while SRH was 300 m2/s2, and the supercell composite parameter was 8 for the Mount Vernon tornado and lower for subsequent tornadoes. MLCAPE was 500-1000 J/kg (higher southeast of the supercell).

The long track cell produced its second Southwest Indiana tornado on the afternoon of July 9th with an EF-1 tornado that began just east of Springfield. A power pole was bent on Oliver Springfield Rd. The tornado tracked to the NNW, damaging a tree grove on Old Beech Creek. Additional tree damage occurred along Old Beech Rd and Lynn Harmony Township Rd with the tornado lifting before reaching Shakerag Rd. Peak estimated winds with this tornado were 105 mph.

The long track cell produced its third Southwest Indiana tornado on the afternoon of July 9th with an EF-2 tornado (peak of EF-0 in Posey County) that began on the north side of Poseyville, just south of I-64. Primarily crop and small branch damage occurred initially as the tornado tracked northeastward with corn fields flattened. As it approached the Gibson County line the tornado shifted to a more northward trajectory, continuing into Gibson County. Estimated peak winds with the Posey County portion of the tornado were 75 mph.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

NWS Paducah, KY wrote its last area forecast discussion before the tornado touched down at Jul 9, 4:03 PM CDT, 29 minutes earlier. Its key messages:

• The remnants of Beryl will gradually lift northeast out of the Quad State tonight. Isolated storms will continue to pose a tornado and flash flooding threat over the Pennyrile region of west Kentucky and Evansville Tri State through early evening.
• Isolated showers and storms will be possible Wednesday through Thursday, but temperatures will be a few degrees below normal.
• High pressure aloft builds in through the weekend, resulting in temperatures well into the 90s. Heat indices will reach the triple digits by Sunday and could climb over 105 degrees early next week.

.DISCUSSION...
Issued at 403 PM CDT Tue Jul 9 2024

A north/south oriented boundary located from near Harrisburg
Illinois to Murray Kentucky has a broken line of showers and
storms along it. The boundary separates cooler air behind it from
the tropical soup ahead of it. Scattered thunderstorms ahead of
the line remain capable of producing tornadoes and damaging
winds. The widespread heavy rains have not really developed over
the region today and we have already cancelled western portions
of the Flood Watch. However, along and ahead of the boundary,
locally heavy rainfall still has the potential to briefly
overwhelm drainage systems and result in some flooding issues.
So will keep the Flood Watch going along and ahead of the boundary
into this evening. The Flood Watch will likely be cancelled well
before its 12Z Wednesday expiration.

As Beryl lifts northeast, another upper disturbance will rotate
southward through the Mississippi Valley Wednesday into
Thursday. Much of the 12Z and later guidance generates some
isolated convection associated with this feature Wednesday
through Thursday. Decided to insert some slight chance PoPs to
account for the possibility.

High pressure aloft will build northward over the Quad State
Friday into Saturday, but lower-amplitude troughing will linger
to the north/northeast of the region. The ridging should win out
over the Quad State and keep the area dry through the weekend
and into early next week. Temperatures will climb up above
normal by Saturday and reach the middle 90s Sunday through next
Tuesday. Persistent south winds will eventually bring
significant low-level moisture back to the region, allowing heat
indices to climb into the triple digits Sunday and possibly over
105 Monday and Tuesday.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1236 PM CDT Tue Jul 9 2024

Really tricky forecast this period with cigs bouncing around,
and precip off and on thanks to the remnants of Beryl. Cigs are
mainly MVFR with occasional IFR passing through until later in
the period when IFR may persist more. Showers and storms are
expected to impact the terminals at various times throughout the
period due to remnants of Beryl passing through. This may
decrease visibility at times. Wind is also expected to increase
overnight particularly around the Evansville Tri-State with
gusts to around 20-25 kts at times.

This Hazardous Weather Outlook is for portions of southern
Illinois, southwest Indiana, western Kentucky, and southeast
Missouri.

.DAY ONE...Tonight

Severe storms with primarily a tornado threat will continue across
the Evansville Tri State and the Pennyrile region of west Kentucky
into the early evening. Locally heavy rainfall will accompany the
thunderstorms, and could lead to some brief, relatively minor
flooding issues, as drainage systems are briefly overwhelmed by
the tropical rains. The Flood Watch continues mainly east of the
Mississippi River.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Minor river flooding is forecast to continue and may increase due
to the remnants of Beryl.

Isolated thunderstorms will be possible Wednesday into Thursday. A
brief heavy downpour and lightning will be the main concerns.

Triple digit heat indices will be possible throughout the region
Sunday and Monday.

.SPOTTER INFORMATION STATEMENT...

Spotters over the Evansville Tri State and Pennyrile region of
west Kentucky should be active with the Tornado Watch in effect.

10 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
